Comedy

Stand-up. Characters. Sketches. Songs. A little bit of chaos.

I’m Marina O’Shea, a comedian, writer and performer based in the South West. I perform stand-up and character comedy across the UK, with a particular fondness for sharp observations, playful storytelling and ridiculous characters.

My comedy tends to sit somewhere between the everyday and the completely absurd. I like finding the funny in awkward situations, questionable decisions and the things we probably shouldn’t say out loud.

I’ve performed at comedy clubs, theatres and festivals around the UK, written for The What The Frock! Book of Funny Women and performed with various stage and screen companies, developing a style that moves between stand-up, character comedy, sketches and musical comedy.

Expect smart, silly, slightly surreal comedy – delivered with warmth, wit and a mischievous edge.

Marina & The Diamantes

Coming to venues in 2027

Sparkle, silliness and just a touch of chaos.

Marina & The Diamantes is my brand-new comedy show, bringing together stand-up, character comedy, sketches and musical numbers in one gloriously unpredictable night.

Developed from my stand-up work around the UK in 2025, I’m joined by performers Lizi Bennett and Juliet Chappell for a whirlwind of sharp observations, shared stories, outrageous characters and songs that are equal parts clever and ridiculous.

The show made its debut at Barbican Theatre, Plymouth in 2026, as part of Plymouth Performance Festival, and will tour in 2027.

Expect laughter, unexpected songs, ridiculous personas and the occasional moment of:

“What did I just see?”

Smart, silly and sparkling.

A little bit of history…

O’Shea & O’Gaukroger

Before going solo, I spent seven glorious years as one half of sketch comedy duo O’Shea & O’Gaukroger.

We were described as:

“Like Morecambe and Wise. But with boobs.”

“A young Wood & Walters”

“The funniest women in the world” (David Quantock – writer, The Thick Of It, Harry Hill’s TV Burp, Smack the Pony’).

We were finalists for Bath Comedy Festival Best New Act and toured nationally with multiple shows, developing a reputation for surreal, character-driven comedy and a distinctly silly take on the world around us.

Our work featured on BBC Radio Bristol and screened at the London Short Film Festival, alongside appearances at comedy clubs, theatres and festivals across the UK, including a fantastic run at the Edinburgh Fringe Festival.

These days, I’m working as a solo comedian, bringing many of the same ingredients – characters, silliness, storytelling and a healthy disregard for dignity – into my stand-up and new live work.

It All Started With An Aubergine…

It really did.

Many moons ago, I created my first comedy character: Wolfgang, a painfully serious open-mic jazz poet with a particular passion for vegetables.

Especially aubergines.

Wolfgang was the character that started my journey into comedy, eventually leading to seven years of touring with O’Shea & O’Gaukroger and, later, my move into solo stand-up and character comedy.

Somewhere along the way, the aubergine became less important.

The silliness did not.
